- Application Mai-t1. 6,1950, Serial No. 147,807 1 3 ol iinsl (01. 243-229) I This invention relates-to an arm support for use in conjunctionwith operating beds or tables,

being primarily concerned with a novel, practical and very usefulsupport for the arm of a surgeon, or others engaged in an operation, forsteadying the arm and supporting it.

It is an object and purpose of the present invention to provide anarmsupport which may be mounted for adjustment to any desired position inthe length of the bed, is also adjustable for a swinging movement todifferent angular The. ears -Imand. Illafa're. mounted for angularpositions, and further adjustable vertically for obtaining the rightheight for the rest or support of the arm.

An understanding of the invention may be had from the followingdescription, taken in connection with the accompanying drawing, inwhich,

Fig. 1 is a perspective view showing the arm support of my inventionattached to an operating bed, shown fragmentarily. 1

Fig. 2 is a side elevation of the arm support, the rail on the bed onwhich the support is mounted being shown in vertical cross section.

Fig. 3 is a horizontal section on the plane ofline 3-3 of Fig. 2.

Likereference characters refer to like parts in the difierent figures ofthe drawing.

In the structure of the arm support, an elongated plate I of thin metal,which in practice may be aluminum, has downturned flanges 2 at itslongitudinal side edges, the juncture of said flanges and the sides ofthe plat I being raised slightly in longitudinal rims 3, one at eachside of the plate I, upon which the arm is to rest. Said plate I, ateach end, is extended as indicated at 4 and curved or bent downwardslightly The post 5 extends through the loop 8 and is adjustable todifferent positions. It is clamped and held in any desired position bytightening the screw at 9.

A slidably mounted bracket ID has an intermediate vertical portion, andat its upper end an overhanging shoe II. Adjacent its lower endextending oppositely from the shoe II, is an ear Illa located underneatha complementary ear la at the end of the bracket! opposite the loop 8.

adjustment with respect to "each other and are held in a position wantedbytightening a clamping screw I2.

At the lower end of the intermediate vertical section of theslidemounting I0, a block I3 is located through which the lower end of ascrew I4 passes for vertical movement of the block I3. The block I3 is aholding or clamping block which tightens against the under edge of a barI5, located at a side of a surgical bed or table I6. Thus the structureis adjustably mounted on the horizontal bar I5 and is held in anyselected position to which moved by tightening the screw I4. The bracketI may be swung to difierent angular positions and held by tightening thescrew at I2, and the post 5 and connected parts are adjustablevertically within the limits of the length of the post and are held in aselected osition by tightening the screw at 9.

The overhanging shoe I I is stepped on its under side so that it willreceive bars I5 of different widths. V

The construction described is practical and useful. The arm resting onthe plate I is supported against accidental or other undesired movementand is of utility in connection'with surgical beds and tables.

The invention is defined in the appended claims and is to be consideredcomprehensive of all forms of structure coming within their scope.

I claim:

1. In a. structure of the class described, a bracket having a verticalportion and a shoe extending horizontally from the upper end portionthereof to one side, adapted to ride upon a horizontal bar support,means for releasably clamping said bracket to a horizontal bar support,said bracket having an ear integral therewith extending from itsvertical portion opposite to said shoe, a member pivotally connected atone end to said ear to turn about a vertical axis, and extending awaytherefrom generally in the same direction as said car, a vertical post,and means for adjustably connecting said post to the opposite endportion of said member, and for releasably holding said post in anyposition to which adjusted.

2.'In a structure of the class described, a bracket having a verticalportion adapted to lie alongside of a vertical side of a horizontal barsupport, and having an integral shoe at its upper end adapted to extendover and ride upon the upper edge of said bar support, releasable,manu-- ally operable clamping means for clamping said bracket atdifferent adjusted positions thereof post at the outer end of saidmember for vertical.

adjustment combined-with means for releasably securing said post in aselected adjusted position.

3. In a structure of the class described, a clamp including a verticalsection, anda laterally ex tending shoe at its upper portion adapted toride on a horizontal carrying bar,-a clamping block located at the lowerend of the said vertical sec tion, adapted to bear against'the underside of said bar, screw means for drawing said block into Numberclamping position, said vertical section having a laterallyextendingear, an arm having an car at one end overlapping said firstmentioned ear,

means for pivotally connecting the two ears and for clamping themtogether to secure them in adjusted position relative to each other,said arm at its outer end having an integral loop providing a verticalpassage, a post extending through the passage in said loop-, and meansto clamp the loop against said post.
